  vq30de from a I30?


Does any one ever do anything with these engines, I see a lot of threads on vq30dets which I assume is a non US engine? or just a vq30de with a turbo added on to it?

But it is the normal maxima/i30 engine good, as in reliable, makes good power, semi upgradable(not looking for huge power but capible of holding 6-10lbs of boost from say a t3 size turbo, like one from a vg30et).

Just looking for a better sounding and more powerful non aspirated engine than the vg30et, the vg30et is a great engine, its just not stock non turbo, That is all ive dealt with car wise and im looking to put a dohc v6 in a 73 toyota truck I have. And I really want a vq35, those sound so good and make great power, but I dont want to spend that much, I think I can get a vq30de and a 350z 6spd for under a grand... and source the ecu and eletronics from various junkyards... and I read it makes 190hp, that should be great in a light truck.

Im just looking for the flaws of this engine

And is there a write up on using the vq35 6spd on a vq30de, I think ive read the only thing is using the vq35 flywheel and clutch?

Also one more thing, are these front or rear sumps? I assume they are front because my 1990 maxima was front sump, but I wouldnt be surpised if they changed it in 95.

Edit: and was looking at the I30 some more and they made almost 230hp in 2000+, is there anything different with that engine? What made it have more power? Does it have to do with the intake? could I use electronics from say a 95+ with the later engine, they are around the same price as the 95-2000. If I am going to do all this work I might as well spend the extra 250 bucks and get the better engine, unless It requires a lot more wiring or more expensive ecus or something like that.

I couldn't tell you anything about boosting the vq30. This same engine is also in the 95-99 maxima. The more powerful vq30 is in the 00-01 maximas, not sure about which I30 years though.

Only quirks I can think of at the moment are the water pump and coil packs..

Heres some info on the 6-speed swap http://forums.maxima.org/all-m....html There is TONS of information on maxima.org. Check it out if you haven't already.

Don't know about sumps.

The main reason the newer vq30, vq30de-k, makes more power is due to the intake manifold. You can swap the intake manifolds over. This is referred to as an 00vi swap (2000 variable intake). You will need an rpm switch, or vafc to activate the VIAS in the intake manifold if you do swap it over to the older engine.

Hope this helps!
